dosDecryptFile(string FileName, string DecryptedFileName, string Key)

Decrypts the file specified by FileName and stores the decrypted contents of the file in the file specified by DecryptedFileName. The decryption is done with the use of Key. This method can be used to decrypt files encrypted by the dosEncryptFile() method with key having the same value as when the dosEncryptFile() method was called to encrypt FileName.
 

Parameters :

FileName : A string specifying the full path name of the file to decrypt.
DecryptedFileName : A string specifying the full path name of the target decrypted file. If this string is the same as FileName then the decrypted file will overwrite the original file.
Key : A string specifying the key to decrypt with. Key may be of any length. If Key is an empty string no decryption will be made and the target file specified by DecryptedFileName will be identical to the source file specified by FileName.

Return Value : An integer indicating whether the method was successful or not. If 1 is returned, the method was successful. If 0 is returned, the method was not successful in which case dosGetLastError() should be called to determine the cause of the error. 

Possible Returned Error Codes via dosGetLastError() :
10016 : Invalid file name specified. 
10020 : File is write disabled. Could not write encrypted code back to file.
